Do I need DEET if I'm using a spatial repeller?

For stationary use on a patio, deck, or campsite, reviewers across camping and outdoor subreddits report a Thermacell-style spatial repeller is often sufficient. For hiking, yard work, or any activity where you're moving around, the consensus is to still wear a topical repellent (DEET or picaridin) because you keep walking out of the protected zone.
